Research On Application Of Virtual Reality Technology In Electrical Safety Experimental Teaching

In electrical safety teaching courses,electrical accidents and electrical fire and explosion protection are important teaching parts and key chapters that students must master.However,due to the difficulty in recurring electrical accidents in teaching,the danger and harm,the short teaching time,the boring course teaching,and the large number of students,the students are difficult to understand,not motivated to learn,and the knowledge conversion rate is low.Aiming at the deficiencies in teaching,taking electrical accidents and electrical fire-proof and explosion-proof course experiments as the research objects,the electrical safety virtual simulation teaching system based on virtual reality technology is designed and developed.The main research contents are as follows:(1)Through the analysis of a variety of electrical safety accidents,including electrical ignition sources,electrical equipment fire extinguishing,electrical shock,and electric shock rescue,combined with the current research status of virtual reality technology in electrical safety teaching,we can find teaching in a targeted manner At the same time as the entry point of technology,the design scheme of the virtual simulation teaching system of electrical safety is proposed.At the same time,it analyzes the virtual reality technology,AI technology,and psychological behavior correction technology used in the system development,which provides theoretical support for reducing the bad behavior of on-site operators.(2)Discusses the production process of 3D model,the production process of skeletal movement and the technical method of simplifying the model.Taking the transformer as an example,the production route of geometric modeling,UV unfolding,texture drawing,and three-point lighting is elaborated.Finally,the 3D video production steps are analyzed,and the course teaching video is developed using nonlinear editing technology combined with Premiere and AE software.Completed the preparation of the underlying resources,laying the foundation for later interaction.(3)Based on the Visual Studio platform and C# language,the UI program framework,capsule controller,intelligent AI module,and motion sickness reduction methods were developed.The UI elements of the system are designed based on PS image processing technology.The system has developed a variety of roaming methods,which realizes lowcost roaming by combining mobile phones with handles,which improves the flexibility of teaching and reduces the cost of hardware equipment.(4)Based on the Unity3 d engine design and development of the experimental teaching module,video learning module,scene roaming module,theoretical examination module,the role state machine was made using the action controller,the light rendering technology was used to set off the scene,and the particle module was used to make explosions and burnings.,Spray and other special effects.Based on My SQL database technology,a module for registration,login,and assessment is developed.Completed system integration.The simulation system integrates teaching operation simulation,video learning,scene roaming and answering test functions,which improves the shortcomings of traditional teaching,can stimulate students’ learning enthusiasm,and has vivid and rich content,flexible operation and high scalability.
